## Grafana dashboard

![Grafana dashboard: runners online/offline/busy, poll health, per-runner online and busy timelines, org repo counts, API rate limit and open PRs](docs/dashboard.png)

[`dashboards/github-actions-runner-exporter.json`](dashboards/github-actions-runner-exporter.json) covers every metric above:
- runners online, offline and busy, with per-runner state timelines;
- both exporter polls' health, so a stale cache is visible;
- CI health per repo and workflow, open PRs, Dependabot alerts by severity, and the API rate limit.

Import it in Grafana (Dashboards → New → Import) and pick your Prometheus data source.
